aen of the United States, residing at New York, in the countyof New York and Statev 1 of New York, have invented certain new and useful Improvements in Sewing-Machine Hoppers; and ll do hereby declare theffcllowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaiiis to make and use the same.

rlhis invention relates to sewing machine hoppersand more particularly to that type of receptacles carried b a sewing machine bed to receive the work rom the sewing machines commonly used in large establishments.

' hopper which An object of this invention is to provide a ay be attached Ato a sewing machine to rece ve the work from the inachine and'in having said hopper so arranged .as to return the work to the operatoria the order in which the work was done, so that the operator may handle the garments in their which permits each sewing machine having i successive steps in regular order. A. further object of this" invention 1s a provision bt 'a hopper of compact design its individual hopper, to thereby keep the work ot the operatosseparate.-

\ .h tui-ther object ot this invention is a hopper having an inclined bottom which f reeds the work back to the operator by gravity.,

A further object of this invention is' afor the end 'of the hopper and to further,y

receive the unfinished work.

Further objects will be apparent from the following specification, appending claims and drawings, in which- Figure 1 is an end elevation, partly in section, showing the relative arrangement of;

sewing machines so equipped with these hoppers,

transverse sectional view lln factories where largenumbers of sew- I ing machines are used, having said sewing machines so arranged vas-to receive ower from a common shaft, it is desirous o hav ing means for taking care of the partly hnished work from the operators in such a l method as to prevent the work of the oppositey operator becoming' mixed, and Awhere garments are made whichrequire several steps in the production thereof, it is customary for the operator to work on said `garments by producing the irst step in 'each garment, and then passing -eacli garment through the machine successively for the tol-y rated from each other. vln this invention,

for taking the garments in a partly finished form an returning the same to a convenient position for the operator to handle in passing through the machine :tor the second opera.- tion.

Referring 'to the drawings in which the several features of this invention are clearly indicate sewing machine usual frames 13, and supported by these frames are the pulleys 14 and 15, of which the pulleys 14: receive the belts 16 which drive the sewing machines, while the pulleys 15 receive the belts 17 which'also pass about the pulleys 18 on a common drive shaftl). The pulley 15 drives the shaft supporting the pulley 1i, but the usual type of clutch mechanism may be employed for connecting the pulley 14C to the driven shaft, and for operating such clutch mechanism l provide a treadle 20, which may be pivotally mounted as at 21 to the bearing block 22. This treadle may be connected to the clutch member as by a chain or 'other connectingA means, 23.v V t The Acommon drive shaft 19 may be supported inthe usual manner, as by standards,

of whichone is shown as zit-24, and this shaft may receive itspower from any prime .mover such as an electric motor or the liken lowing steps until it is finished, at which time the individual garments may be sepa-` `The sewingmachine beds 10 and 11 are in spaced relation but are arranged in parallel relation as in common practice to receive hoppers 25 and 26 therebetween. These hoppers are so arranged as to p ermit interchangeability between the sewin machine beds, and will preferably be of asimilar construction having a raised side wall 27 along one side thereof, the corresponding wall 28 yalong the back thereof, and a diagonally disposed wall 29 which abuts against a corresponding wall of the adjacent member. The bottom 30 is inclined from the side walls 27, 28 and 29, and is of such a pitch as to return the articles placed therein to the operator throu h`the open end 31 of the chute. The si e wall 27 may be plane, but the opposite wall 32 is curved substantially 'as shown, to provide room for the clutch mechanism and pulleys of the sewing machine as well as to aord room for the operators knees. l

rl`heopen end of the chute 31 is normally closed by a container 33 which has one wall .25 thereof hingedly secured as at 34 to the lower end of the side wall 27 and this container may have a series of compartments 35, formed therein to receive work to be handled by the machine. The opposite wall. of this container has a lug 36 formed therein, with which a fastening member 37 carried by the chute co-acts in holding said container in locked relation to the chute. to thereby cause one of the partitions 38 to form a closure for the end of the chute. The container has a cover 39 hingedly secured thereto which may be swung to overlie the several compartments of the container or to assume a position against the end wall of said container, and the container is further provided with legs or supports 40 to keep the bottom of the container in spaced relation to the floor. IThe function of hingedly securing said container to the chute is to preventthe `containers 33 of the several sewing machines from becoming mixed as is common in factories where large numbers of employees are, and by swinging said container to an open position the contents of the chute may be easily removed.

llt is thought that the application and utility of such a chute as this is clearly seen in view of the foregoing, and that the foregoing description clearly defines the general principle of this type of chute. Various modifications may be made within the scope of the pending claims without departing from the spirit of the invention, and no limitation is implied by the limited showin of the drawings.

aving thus described this invention, l claim 1. A hopper for attachment to a work table comprising an inclined bottom to feed work toward the lower end of the bottom, an

enlarged upper end rising behind the rear' edge of the work table, a reduced lower end underlying the forward edge 0f the work table, and said hopper receiving work from over the rear edge of the work table and feedine it to a point under the front edge for subsequent treatment.
